Hi, I'm Sandeep, Creator of JavaByTechie
Senior Java Engineer & Technical Author
I'm a backend engineer with over a decade of experience building large-scale distributed systems using Java, Spring Boot, Kafka and Microservices. I've worked across fintech, e-commerce and SaaS products, and mentored many developers along the way.
I created JavaByTechie to make learning Java simple, practical and interview-focused. Every tutorial comes from real-world experience: no fluff and no outdated examples, just the concepts and code that actually matter.
